Product Description

The TC‑205‑02‑4M5 Allen‑Bradley 40‑channel internal I/O companion slot cable is a Trusted I/O cable designed specifically for internal connection between

output modules and field termination assemblies (FTA) in industrial control systems. It supports up to 40 channels, enabling signal and power

cabling within cabinets or racks. This internal companion cable is often used in PLC and safety systems to

link output modules with corresponding FTA or distribution units efficiently.

Q1: What exactly is an I/O companion slot cable?
A: It is a multi‑core cable assembly used for internal cabinet connections between output modules and FTAs in PLC or safety systems.

It routes multiple signals (40 channels) and power paths in a single harness.

Q2: Which systems does this cable work with?
A: The TC‑205‑02‑4M5 type cable is intended for use with trusted PLC output modules and internal field termination

assemblies. It’s typically paired with Rockwell/Allen‑Bradley Trusted or companion I/O module platforms.

It is not a standard external I/O patch cable, but an internal companion connection.

Q3: Can it be used externally between cabinets?
A: No. This specific cable is designed for internal cabinet wiring. External cables typically

have different shielding, environmental ratings, and connector types.
